Sephina differs from Spartocera in having the posterior margin of the metasternum 
straight ; the nervures of the membrane are furcate ; the disk of the pronotum is convex, 
depressed anteriorly ; and the base of the rostrum is much less incrassated. 
This is a purely Neotropical genus, one species alone being recorded as just entering 
the Nearctic Region. About one half of the genus is peculiar to Central America; and 
the species seem to possess neither wide expanse of range nor variability of character. 
1. Sephina bicornis, n. sp. (Tab. XIII. fig. 7.) 
Black, lateral angles of pronotum with adjoining moieties of lateral and basal margins both above and beneath, 
two discoidal pronotal tubercles, apical half of scutellum, basal margins of corium both above and beneath, 
apex of abdomen above and beneath, a spot situated on apex of apical segment, base of anal appendage, 
and three spots on each side of sternum, situated. near anterior, intermediate, and. posterior coxe, red, 
Connexivum with a segmental row of large luteous spots, which form a marginal Series to abdomen 
beneath. 
Antenne pilose, first and second joints subequal in length, third shortest, and fourth slightly longest. Pro- 
notum obscurely punctate, lateral margins finely denticulate, lateral angles prominent, subacute, slightly 
directed hindwards, and deeply sinuate posteriorly ; discoidal tubercles obtusely subconical and moderately 
prominent. Corium very faintly and obscurely punctate ; lavas more clearly and deeply punctate. 
~ Long. 19 millim., lat. pronot. ang. 8 millim. . 
Hab. Guaremata, Senahu (Champion). 
This species is allied to S. pustudata, Fabr., and forms with that species, in the 
common character of discoidal tubercles to the pronotum, a distinct section of the genus. 
It differs from the Fabrician species by the much less sinuated and rounded lateral 
margins of the pronotum, the less developed discoidal tubercles, and the absence of the 
two discoidal spots on corium.
